CROSS-REFERENCE TO RELATED APPLICATIONS

Any and all applications for which a foreign or domestic priority claimis identified in the Application Data Sheet as filed with the presentapplication are hereby incorporated by reference under 37 CFR 1.57.

BACKGROUND Field

The present disclosure relates to the field of patient monitoringdevices. More specifically, the disclosure relates to portable andhandheld personal health organizers that are adapted to be coupled withpatient monitors that measure physiological characteristics such asblood glucose level, total hemoglobin, SpO₂, methemoglobin,carboxyhemoglobin, and the like.

Description of the Related Art

Caregivers often employ patient monitoring systems or devices, such aspulse oximeters, capnographs, blood pressure cuffs, and the like, forconvenient spot checking and even continuous monitoring of physiologicalcharacteristics of a patient. Patient monitoring systems generallyinclude one or more sensors applied to a patient, a monitoring device,and one or more cables connecting the one or more sensors to themonitoring device.

Portability of these monitoring systems is advantageous for a number ofreasons. For example, portable devices provide the patient with mobilityand provide the caregiver the option of including the monitoring devicewhen transporting patients from one setting to another. Also, caregiversoften transport patients from an ambulance to a hospital emergency room,and between surgical, intensive care, and recovery settings. As anotherexample, portable devices can also provide the patient the capability ofusing the monitoring systems at home or the office.

An example of a patient monitoring device is a glucometer, which is usedin a procedure for measuring glucose concentration in the blood.Glucometers are a key element of home blood glucose monitoring by peoplewith diabetes mellitus or prone to hypoglycemia. A glucometer typicallyprovides a numerical readout of the patient's glucose level. Othermonitor devices may measure physiological characteristics such as totalhemoglobin, SpO₂, methemoglobin, carboxyhemoglobin, etc.

For many conventional patient monitoring devices such as pulse oximetersor glucometers, separate monitoring devices may be needed to measure theoxygen and glucose level saturations. Viewing and analyzing differentphysiological characteristics would also require separate devices.Moreover, conventional patient monitoring devices are limited to thespecialized functions provided by the individual devices, which ofteninclude limited data analysis or synchronization capabilities.

SUMMARY OF THE DISCLOSURE

Embodiments of the present disclosure provide a portable healthorganizer that enables patients and healthcare personnel to managehealth data, and in particular, physiological reading data from one ormore health data collection devices such as a glucometer or pulseoximeter. In an embodiment, the personal health organizer is a dedicatedportable device that is adapted to retrieve reading data from a healthdata collection device, which is a noninvasive device in an embodimentand an invasive device in another embodiment.

In another embodiment, the personal health organizer is a softwaremodule/platform that is configured to be executed on a general purposecomputing device such as a personal computer, a laptop, a mobile phone,a mobile computer, and a wristwatch computer. The general purposecomputer device is directed by the personal health organizer softwaremodule/platform to collect or receive data from either an invasive ornon-invasive health data collection device. Another embodiment is apersonal health organizer device that includes an integrated health datacollection module that is configured to receive physiological datareading from a sensor. The personal health organizer can measure variousphysiological reading data invasively or non-invasively through a sensorconnected through a sensor port in an embodiment.

In an embodiment, the personal health organizer provides seamlessintegration of the reading data with the patient's existing medical dataand with a number of software applications that help a patient manageshis or her health. For example, the physiological reading data, e.g.,blood glucose, total hemoglobin, SpO₂, methemoglobin, carboxyhemoglobin,can be tracked over a time period so the patient is reminded to takemedication and/or perform a new reading. The reminders can be customizedor calculated based on prior medical history and/or personal informationsuch as age and gender stored in the personal health organizer. Asanother example, the reading data can also be forwarded to healthcareproviders such as physicians and pharmacies so they can provide feedbackto the patient. The personal health organizer can also trigger alerts ifthe reading data indicate an abnormal level that requires medicalattention.

In addition to the forgoing, embodiments of the present disclosure alsoprovide electronic medical record (EMR) integration in conjunction withsupport for medical record synchronization across networked locations(e.g. via a cloud computing network). Medical data (including readingdata and other patient-entered data such as medication schedule andactivity/food in-take logs) from the personal health organizer deviceare automatically synchronized with the corresponding records located ata remote entity (e.g. in a centralized EMR storage or at the healthcareproviders' data storage). For example, newly obtained reading data canbe synchronized with a shared, synchronized calendar so that both thephysician and the patient user can adjust an appointment if the readingrequires a change in the appointment schedule. As another example,prescription information can be synchronized so that reimbursements canbe handled automatically when the user finishes a current prescriptionand purchases a new refill. In another example, the personal healthorganizer can initiate the prescription refill process after verifyingdrug interaction and consent of the user and the physician.

In other embodiments, the personal health organizer includes anaccelerometer that detects user motion and the motion can assist in thecollection of and/or display of medical/reading data. For example, theaccelerometer can detect a user's intent to use the device viatouch/motion and automatically start the collection of data when theuser places his or her finger into a sensor associated with a healthcollection data device. In another example, the personal healthorganizer can begin health data collection once the user places his orher finger into a sensor associated with a health collection data deviceand/or provides a gesture via a touch-screen input associated with thepersonal health organizer. In yet another example, the personal healthorganizer begins the data collection when the user places a finger intothe sensor. The LEDs and photo diodes in the sensor can detect thepresence of the finger and initiate data collection. The presence of afinger can be determined, for example, by determining when there is asignificant reduction in detected light. Such a reduction in detectedlight can indicate the presence of a finger and start the datacollection process.

In other embodiments, the personal health organizer includes a number ofhealth education and gaming modules designed to educate the user onhealth management and motivate the user toward a healthier lifestyle.The educational and gaming content can be customized based on the user'scurrent reading data. For example, a tree icon indicative of the user'shealth can be displayed on the personal health organizer, with thehealth of the tree corresponding to the recent readings obtaineddirectly by the personal health organizer through a connected sensor orthrough an associated health data collection device.

For purposes of summarizing the invention, certain aspects, advantagesand novel features of the invention have been described herein. Ofcourse, it is to be understood that not necessarily all such aspects,advantages or features will be embodied in any particular embodiment ofthe invention.

For example, the medical data analysismodule 326 can be used to receive the measurement outputs from themonitor 118 in FIGS. 1B and 2B. As another example, the medical dataanalysis module 326 can be used to receive data from the sensor 116 inFIG. 3B. The medical data analysis module 326 can then analyze the datareceived from the sensor 116 to determine reading data and/ormeasurement values similar to those determined by the monitor 118.

After receiving or determining the reading data, the medical dataanalysis module 326 can perform analysis on the reading data. Forexample, the medical data analysis module 326 can determine bothpre-prandial and post-prandial peak glucose levels. This analysis canhelp healthcare professionals know when and how to titrate medications,especially for patients who are on an insulin sliding scale coverage. Asanother example, the medical data analysis module 326 can determine themean glucose levels (daily, weekly, or monthly, etc.). The medical dataanalysis module 326 can also determine the correlation between thehemoglobin A1c and the glucose levels over a period of time, e.g., a twoto three month period. This can show how well controlled the patient'sblood sugar level is based on the glucose readings from the glucometer.These functions described can be performed by the medical data analysismodule 326, a sub-module, and/or a separate program on the personalhealth organizer.

Medical Data Analysis Module—Data Tracking

In addition to receiving medical data, the medical data analysis module326 can be configured to send collected or stored medical data tointerested parties using the network computing support module 302 and/orthe communications I/O interface module 304. For example, the medicaldata analysis module 326 can send a digital copy of a user's entiremedical record, proof of health insurance, etc. to interested parties,such as a physician office. Medical data including current and pastreadings, reading trends, analyses, medical records, insurance records,can be sent via email, text message, or any other communicationmedium/protocol to any interested party. Likewise, an interested party(e.g. doctor, insurance company) can also send the same type of data tothe personal health organizer via email, text message, or any othercommunication medium/protocol and the attached/transmitted data can beintegrated into the records kept on the personal health organizer.

The medical data analysis module 326 can further include one or moresub-modules or programs for tracking medical data, including readingdata and/or data related patient activities and correlating the medicaldata with patient activities. For example, the medical data analysismodule 326 can track daily food intake that can be downloaded vianetwork 124. In that embodiment, the medical data analysis module 326 isused to receive input from a user, via the input 234 and/or thedisplay/touch panel 206, indicating food taken throughout the day. Thenthe medical data analysis module 326 can store the input in the storage204, analyze the input to determine trends, and/or generate reportsbased on the input. This can help the physician, dietician, or patientto improve or modify dietary strategies for glucose control. In anembodiment, trending data is displayed to the user in various graphicalformats on the display 206 through the medical data display module 344.

As another example, the medical data analysis module 326 can track theglycemic index (GI), which describes the effect of carbohydrates onglucose level, and is sometimes used for medical nutrition therapy. Inanother embodiment, the medical data analysis module 326 can maintain alog of insulin injections given and/or received to show a patient'scompliance with medications. The insulin injections can be input by theuser into the personal health organizer via the user interface on thedisplay 206 or input automatically with digital syringe. The medicaldata analysis module 326 can also generate hypoglycemia or hyperglycemiaalerts. For example, when the received reading data indicates that bloodglucose is too low or too high, the medical data analysis module 326 canalert the patient and prompt the patient to log any symptoms ofhypoglycemia or hyperglycemia. Moreover, the medical data analysismodule 326 can have threshold reading values and/or accompanying symptomchecklists configurable by a physician or a patient, so that if bloodglucose values are detrimentally low or high and/or certain accompanyingsymptoms appear, alerts will be automatically sent to the patient'sphysician or emergency medical personnel. Similarly, the medical dataanalysis module 326 can determine if a user has missed a reading and itcan send alerts (via SMS, email, automated voice call, etc.) to afriend, family member, or a caretaker to check on the user.

Moreover, the medical data analysis module 326 can calculate the amountof insulin to be given based on the user's carbohydrate intake andglucose level post-prandial. This is helpful for patients who are on aninsulin sliding scale coverage. Also, the medical data analysis module326 can perform continuous blood glucose monitoring for patients in ahospital setting or in critical care.

The medical data analysis module 326 can also be configured to manageactivity flags, based on data input by a user. The data input can, byway of example, include: exercise time and severity of exercise, insulin(basal bolus) dosage, medication taken, food (GI index,carbohydrates/proteins) consumed, weight tracking, pulse rate tracking,or CO tracking for smokers. In addition, the tracking can include customflags for other user-defined activities.

In an embodiment, the medical data analysis module 326 works with themedical data display module 344 to provide visualization of health datatracking or trending. In an embodiment, the medical data display module344 displays trended data for a user in a variety of graphical formats,for example, when rotated in a horizontal position. The trended data cancontain continuous or spot readings of measureable parameters or userinput for activity flags, as discussed above.

A skilled artisan would appreciate that the medical data analysis module326 could be associated with different types of programs or applicationsinstalled by the user that can interface with the medical data analysismodule 326. The functions described herein can also be performed by themedical data analysis module 326 alone, one or more sub-modules, and/orone or more separate modules/programs on the personal health organizer.

Theelectronic medical data record integration module 322 and/or the networkcomputing support module 302 can also be configured to synchronizepatient data to centralized medical data servers such as Google Health,Microsoft Health Vault, etc.

The electronic medical data record integration module 322 can alsoenable non-patients such as physicians and family members of a primarypatient user to synchronize patient data with different accessprivileges. For instance, an alias can be created to allow non-trustedsources to review patient data without personally identifiableinformation. The electronic medical data record integration module 322can further enable a user to prove good health practices and complianceto receive special discounted rates or rate cuts from health insuranceproviders. In an embodiment, the electronic medical data recordintegration module 322 and/or the network computing support module 302include an embedded web server that allows access to locally storedhistory, reading/medical data, data settings, and calendar, etc.

The electronic medical data record integration module 322 and thenetwork computing support module 302 can be associated with a calendarprogram. The program can allow a user to synchronize the calendar of thepersonal health organizer with an online synchronized calendar such asOutlook, iCalendar, Google Calendar, Yahoo Calendar, etc. The calendarcan also provide an alarm function, including a smart clock that canstore or access times for scheduled tests and can determine, based onreading data, if more tests are needed (invasive or non-invasive). Asanother example, when a prescription is entered, the personal healthorganizer device in an embodiment tracks medication intake and providesreminders for taking the prescribed medication.

In addition, the electronic medical data record integration module 322can be configured such that the personal health organizer can be used bymultiple users. For example, each user's data can be tracked separatelyon the same device. As a result, for instance, one family would onlyhave to buy one device for spot checking, and family members can loginvia a password or a biometric identification system as further describedbelow. As another example, an endocrinologist office could purchasepatient licenses and store the data of patients the office spot-checks,with the patient records separated by identification tags and protectedvia the security features described herein. A skilled artisan wouldappreciate that the users' medical data (including insuranceinformation) could be stored separately on the personal health organizeror a remote system, e.g., an Electronic Medical Record (EMR) serverlocated on a remote computing network (e.g. cloud computing network).

In an embodiment, the medical data stored on the personal healthorganizer can be retrieved by an EMS or a first responder through theuse of a Rad 57 or similar device. A physician can also perform dataretrieval using a similar device. In another embodiment, the electronicmedical data record integration module 322 can be configured to managemedical expenses and reimbursements. The electronic medical data recordintegration module 322 can be used to track health items purchased bythe user and synchronize the items with a medical expense account. Thepurchased items can also be compared by a comparison shoppermodule/program for best prices and alternative products. The purchasehistory information can also be sent to insurance companies forreimbursement of co-pay overages, for example.

In another embodiment, the network computing support module 302 can beconfigured to provide reminders to the user if the personal healthorganizer is not with the user. For example, the user can call thepersonal health organizer via phone or send an email or text messagewith a particular question regarding appointment times, medicationintake schedule, etc. In an embodiment, the personal health organizer ora data server with synchronized medical data records within a remotecomputing network (e.g. cloud computing network) provides answers to theparticular questions sent.

Since diabetic patients are likely users of the personal healthorganizer and diabetes can sometimes lead to vision impairment, in anembodiment the electronic medical data record integration module 322 isconfigured to synchronize eye care prescription requirement dates andvision check-ups on a calendar. In an embodiment, the personal healthorganizer includes software for testing the user's vision on the deviceto determine if a new prescription is needed. The testing software caninclude Ishihara plates and distance charts displayed on the display206, with the displayed testing materials sized according to an arm'slength testing distance.

In yet another embodiment, the electronic medical data recordintegration module 322 is configured to coordinate prescription. Forexample, once a user's physician verbally mentions a prescription, thepersonal health organizer can acoustically identify the drug term andsearch for generic alternatives. Once the physician agrees to the drug(either the branded drug or the suggested generic alternative), theelectronic medical data record integration module 322 is configured inan embodiment to locate a closest pharmacy (using the built-in GPSand/or triangulation software based on cell tower location) with thebest price and provides contact information of the pharmacy to the user.It can also provide the pharmacy information to a remote computingnetwork (e.g. cloud computing network) for data synchronization or sendit directly to the user's physician so that he or she can submit anelectronic prescription.

Various embodiments of the personal health organizer also provide forexchange of medical data and related information via email. For example,while a caregiver is taking a reading or measurement of a patient withthe personal health organizer, the caregiver can ask the patient whetheror how the patient would like to receive information relating to themeasurement, and if the patient prefers email or text messages, theemail or text message format. The caregiver can input thesecommunication preferences and send an email or text message to thepatient at the point of measurement. In one embodiment, an email of thereading or measurement is automatically sent to the patient upon thecompletion of measurement process. In another embodiment, the email issent later at the direction of the caregiver user or at a timeconfigured by the caregiver user. The email or text message could alsobe routed to additional supervising caregivers, medical recordspersonnel or files, others in the health providing mechanism for aparticular patient, or the like. In some embodiments, federal, state,local, caregiver facility rulemaking bodies may place requirements onthe distribution and/or content of the information, including, forexample, the level of permission required for certain types of databased on, for example, the content thereof. In those instances, thepersonal health organizer may advantageously ask the caregiver at thepoint of measurement to acquire the appropriate permissions, or withholdsending the email or text message until such permissions are processed,authenticated, verified, or otherwise checked and approved or the like.In other embodiments, the personal health organizer may review theavailable permissions and appropriate rule authorities and determine theformat and content of the email or text message that is available forsending. For example, the personal health organizer may include lessinformation, less detailed information, different groupings of medicaland/or personal information based on a particular patient's permissionsand/or applicable medical data disclosure rules. Other forms ofelectronic communications can also be used, for example, information canbe posted to a website, such as a private blog. Information can also besent through various other information posting websites such as, forexample, Twitter™.

None, some, or all of the information relating to patient interactionswith the personal health organizer can be sent electronically. Forexample, emails may be sent to those patients (e.g. an outpatient) thatmay take measurements on their own or have them taken by anon-professional caregiver such a family member. Emails, text messages,or other electronic communications can also include reminders, requestsfor data, advice based on data obtained, or any other similar personalor medical information.

Electronic Medical Data Integration Processes

FIGS. 6A and 6B show methods for integrating medical data records inaccordance with embodiments disclosed herein. At block 352, in anembodiment, a signal indicative of the patient physiological reading isreceived and/or detected at a sensor of the personal health organizer(or an associated health data collection device). At block 354, thepersonal health organizer (or an associated health data collectiondevice) can process the signal to derive or calculate reading data (e.g.derive blood glucose level based on signal received). At the block 360,the reading data can be stored locally (e.g. in the storage 204) alongwith other medical data of the patient user. At block 362, the personalhealth organizer can use the reading data to customize local content atthe personal health organizer, including games and educationalmaterials. At block 364, the personal health organizer can use thereading data to generate health reminders and/or recommendations thatare personalized for the patient user.

At block 356, the reading data can be forwarded to a remote electronicmedical storage. In an embodiment, related medical data can be forwardedwith the reading data as well. At block 372, the records kept at acentralized medical data storage can be synchronized with the forwardedreading data and/or related medical data. At block 374, the forwardedreading data and/or medical data can be used to generate alerts tohealthcare providers. At block 376, the records kept at healthcareproviders can be synchronized with the forwarded reading data and/ormedical data. The healthcare providers can use the forwarded data togenerate feedback such as alerts, data updates, and diagnoses, which arereceived at the personal health organizer at block 358 in accordancewith an embodiment.

The synchronization of data records is further illustrated in FIG. 6B,where a patient 420 is shown to provide reading data to a personalhealth organizer 402, which in turns forwards the reading data and/orother related medical data of the patient 420 to a network 124. Thenetwork 124 can include a remote computing network (e.g. cloud computingnetwork) comprising of LANs, WANs, and the Internet. The reading datacan be relayed to healthcare providers 404, who can provide feedbacksuch as alerts, reminders, and/or diagnoses to the personal healthorganizer 402 via the network 124. The healthcare providers 404 can alsosynchronize their records based on the forwarded reading data (and/orrelated medical data) and in turn provide synchronized and/or updatedmedical data back to the personal health organizer 402. Similarly, thereading data (and/or related medical data) can be forwarded to theelectronic medical record storage 406 via the network, and theelectronic medical record storage 406 can synchronize its records basedon the forwarded reading data (and/or related medical data) and in turnprovide synchronized and/or updated medical data back to the personalhealth organizer 402 via the network. The returned results from thehealthcare providers 404 and/or the electronic medical record storage406 can be displayed back to the patient 420 and/or used by the personalhealth organizer for other purposes such as completing financial costsand deductions to users' medical expense accounts.

Example Health Data Collection Device

FIG. 7 illustrates an example of a health data collection device 112. Inthe depicted embodiment, the monitoring device 118 includes a fingerclip sensor 116 connected to a monitor 118 via a cable 452. In theembodiment shown, the monitor 118 includes a display 456, controlbuttons 454 and a power button. Moreover, the monitor 118 canadvantageously include electronic processing, signal processing, anddata storage devices capable of receiving signal data from said sensor116, processing the signal data to determine one or more outputmeasurement values indicative of one or more physiological parameters ofa monitored patient, and displaying the measurement values, trends ofthe measurement values, combinations of measurement values, and thelike.

The cable 452 connecting the sensor 116 and the monitor 118 can beimplemented using one or more wires, optical fiber, flex circuits, orthe like. In some embodiments, the cable 452 can employ twisted pairs ofconductors in order to minimize or reduce cross-talk of data transmittedfrom the sensor 116 to the monitor 118. Various lengths of the cable 452can be employed to allow for separation between the sensor 116 and themonitor 118. The cable 452 can be fitted with a connector (male orfemale) on either end of the cable 452 so that the sensor 116 and themonitor 118 can be connected and disconnected from each other.Alternatively, the sensor 116 and the monitor 118 can be coupledtogether via a wireless communication link, such as an infrared link,radio frequency channel, or any other wireless communication protocoland channel.

The monitor 118 can be attached to the patient. For example, the monitor118 can include a belt clip or straps that facilitate attachment to apatient's belt, arm, leg, or the like. The monitor 118 can also includea fitting, slot, magnet, snap-click connector (e.g., connectorsmanufactured by LEMO S.A. of Switzerland), or other connecting mechanismto allow the cable 452 and sensor 116 to be attached to the monitor 118.

The monitor 118 can also include other components, such as a speaker,power button, removable storage or memory (e.g., a flash card slot), anAC or DC power port, and one or more network interfaces, such as auniversal serial bus interface or an Ethernet port. For example, themonitor 118 can include a display 456 that can indicate a measurementfor glucose, for example, in mg/dL. Other analytes and forms of displaycan also appear on the monitor 118.

In addition, although a single sensor 116 with a single monitor 118 isshown, different combinations of sensors and device pairings can beimplemented. For example, multiple sensors can be provided for aplurality of differing patient types or measurement sites or evenpatient fingers.

FIG. 8 is a block diagram that illustrates the components of an exampleof a health data collection device 112. In certain embodiments, thehealth data collection device 112 noninvasively measures a bloodanalyte, such as oxygen, carbon monoxide, methemoglobin, totalhemoglobin, glucose, proteins, glucose, lipids, a percentage thereof(e.g., saturation) or for measuring many other physiologically relevantpatient characteristics. The device 112 can also measure additionalblood analytes and/or other physiological parameters useful indetermining a state or trend of wellness of a patient.

The data collection device 112 can be capable of measuring opticalradiation from the measurement site. For example, in some embodiments,the data collection device 112 can employ photodiodes defined in termsof area. In an embodiment, the area is from about 1 mm²-5 mm² (orhigher) that are capable of detecting about 100 nanoamps (nA) or less ofcurrent resulting from measured light at full scale. In addition tohaving its ordinary meaning, the phrase “at full scale” can mean lightsaturation of a photodiode amplifier (not shown). Of course, as would beunderstood by a person of skill in the art from the present disclosure,various other sizes and types of photodiodes can be used with theembodiments of the present disclosure.

The data collection device 112 can measure a range of approximatelyabout 2 nA to about 100 nA full scale. The data collection device 112can also include sensor front-ends that are capable of processing andamplifying current from the detector(s) at signal-to-noise ratios (SNRs)of about 100 decibels (dB) or more, such as about 120 dB in order tomeasure various desired analytes. The data collection device 112 canoperate with a lower SNR if less accuracy is needed for an analyte likeglucose.

The data collection device 112 can measure analyte concentrations,including glucose, at least in part by detecting light attenuated by ameasurement site 502. The measurement site 502 can be any location on apatient's body, such as a finger, foot, ear lobe, or the like. Forconvenience, this disclosure is described primarily in the context of afinger measurement site 502. However, the features of the embodimentsdisclosed herein can be used with other measurement sites 502.

In the depicted embodiment, the device 112 includes an optional tissuethickness adjuster or tissue shaper 522, which can include one or moreprotrusions, bumps, lenses, or other suitable tissue-shaping mechanisms.In certain embodiments, the tissue shaper 522 is a flat or substantiallyflat surface that can be positioned proximate the measurement site 502and that can apply sufficient pressure to cause the tissue of themeasurement site 502 to be flat or substantially flat. In otherembodiments, the tissue shaper 522 is a convex or substantially convexsurface with respect to the measurement site 502. Many otherconfigurations of the tissue shaper 522 are possible. Advantageously, incertain embodiments, the tissue shaper 522 reduces thickness of themeasurement site 502 while preventing or reducing occlusion at themeasurement site 502. Reducing thickness of the site can advantageouslyreduce the amount of attenuation of the light because there is lesstissue through which the light must travel. Shaping the tissue in to aconvex (or alternatively concave) surface can also provide more surfacearea from which light can be detected.

The embodiment of the data collection device 112 shown also includes anoptional noise shield 526. In an embodiment, the noise shield 526 can beadvantageously adapted to reduce electromagnetic noise while increasingthe transmittance of light from the measurement site 502 to one or moredetectors 506 (described below). For example, the noise shield 526 canadvantageously include a conductive coated glass or metal gridelectrically communicating with one or more other shields of the sensor116 or electrically grounded. In an embodiment where the noise shield526 includes conductive coated glass, the coating can advantageouslyinclude indium tin oxide. In an embodiment, the indium tin oxideincludes a surface resistivity ranging from approximately 30 ohms persquare inch to about 500 ohms per square inch. In an embodiment, theresistivity is approximately 30, 200, or 500 ohms per square inch. Aswould be understood by a person of skill in the art from the presentdisclosure, other resistivities can also be used which are less thanabout 30 ohms or more than about 500 ohms. Other conductive materialstransparent or substantially transparent to light can be used instead.

In some embodiments, the measurement site 502 is located somewhere alonga non-dominant arm or a non-dominant hand, e.g., a right-handed person'sleft arm or left hand. In one embodiment, the data collection device 112can recognize a user's or patient's non-dominant arm/hand by comparingthe two arms/hands according to various types of physiologicaldata/measurements. For example, in some patients, the non-dominant armor hand can have less musculature and higher fat content, which canresult in less water content in that tissue of the patient. Tissuehaving less water content can provide less interference with theparticular wavelengths that are absorbed in a useful manner by bloodanalytes like glucose. Accordingly, in some embodiments, the datacollection device 112 can be used on a person's non-dominant hand orarm.

The data collection device 112 can include a sensor 116 (or multiplesensors) that is coupled to a processing device or physiological monitor118. In an embodiment, the sensor 116 and the monitor 118 are integratedtogether into a single unit. In another embodiment, the sensor 116 andthe monitor 118 are separate from each other and communicate one withanother in any suitable manner, such as via a wired or wirelessconnection. The sensor 116 and monitor 118 can be attachable anddetachable from each other for the convenience of the user or caregiver,for ease of storage, sterility issues, or the like. The sensor 116 andthe monitor 118 will now be further described.

In the depicted embodiment shown in FIG. 8, the sensor 116 includes anemitter 504, a tissue shaper 522, a set of detectors 506, and afront-end interface 508. The emitter 504 can serve as the source ofoptical radiation transmitted towards measurement site 102. As will bedescribed in further detail below, the emitter 504 can include one ormore sources of optical radiation, such as LEDs, laser diodes,incandescent bulbs with appropriate frequency-selective filters,combinations of the same, or the like. In an embodiment, the emitter 504includes sets of optical sources that are capable of emitting visibleand near-infrared optical radiation.

In some embodiments, the emitter 504 is used as a point optical source,and thus, the one or more optical sources of the emitter 504 can belocated within a close distance to each other, such as within about a 2mm to about 4 mm. The emitters 504 can be arranged in an array, such asis described in U.S. Publication No. 2006/0211924, filed Sep. 21, 2006,titled “Multiple Wavelength Sensor Emitters,” the disclosure of which ishereby incorporated by reference in its entirety. In particular, theemitters 504 can be arranged at least in part as described in paragraphs[0061] through [0068] of the aforementioned publication, whichparagraphs are hereby incorporated specifically by reference. Otherrelative spatial relationships can be used to arrange the emitters 504.

For analytes like glucose, currently available non-invasive techniquesoften attempt to employ light near the water absorbance minima at orabout 1600 nm. Typically, these devices and methods employ a singlewavelength or single band of wavelengths at or about 1600 nm. However,to date, these techniques have been unable to adequately consistentlymeasure analytes like glucose based on spectroscopy.

In contrast, the emitter 504 of the data collection device 112 can emit,in certain embodiments, combinations of optical radiation in variousbands of interest. For example, in some embodiments, for analytes likeglucose, the emitter 504 can emit optical radiation at three (3) or morewavelengths between about 1600 nm to about 1700 nm. In particular, theemitter 504 can emit optical radiation at or about 1610 nm, about 1640nm, and about 1665 nm. In some circumstances, the use of threewavelengths within about 1600 nm to about 1700 nm enable sufficient SNRsof about 100 dB, which can result in a measurement accuracy of about 20mg/dL or better for analytes like glucose.

In other embodiments, the emitter 504 can use two (2) wavelengths withinabout 1600 nm to about 1700 nm to advantageously enable SNRs of about 85dB, which can result in a measurement accuracy of about 25-30 mg/dL orbetter for analytes like glucose. Furthermore, in some embodiments, theemitter 504 can emit light at wavelengths above about 1670 nm.Measurements at these wavelengths can be advantageously used tocompensate or confirm the contribution of protein, water, and othernon-hemoglobin species exhibited in measurements for analytes likeglucose conducted between about 1600 nm and about 1700 nm. Of course,other wavelengths and combinations of wavelengths can be used to measureanalytes and/or to distinguish other types of tissue, fluids, tissueproperties, fluid properties, combinations of the same or the like.

For example, the emitter 504 can emit optical radiation across otherspectra for other analytes. In particular, the emitter 504 can employlight wavelengths to measure various blood analytes or percentages(e.g., saturation) thereof. For example, in an embodiment, the emitter504 can emit optical radiation in the form of pulses at wavelengthsabout 905 nm, about 1050 nm, about 1200 nm, about 1300 nm, about 1330nm, about 1610 nm, about 1640 nm, and about 1665 nm. In anotherembodiment, the emitter 504 can emit optical radiation ranging fromabout 860 nm to about 950 nm, about 950 nm to about 1100 nm, about 1100nm to about 1270 nm, about 1250 nm to about 1350 nm, about 1300 nm toabout 1360 nm, and about 1590 nm to about 1700 nm. Of course, theemitter 504 can transmit any of a variety of wavelengths of visible ornear-infrared optical radiation.

Due to the different responses of analytes to the different wavelengths,certain embodiments of the data collection device 112 can advantageouslyuse the measurements at these different wavelengths to improve theaccuracy of measurements. For example, the measurements of water fromvisible and infrared light can be used to compensate for waterabsorbance that is exhibited in the near-infrared wavelengths.

As briefly described above, the emitter 504 can include sets oflight-emitting diodes (LEDs) as its optical source. The emitter 504 canuse one or more top-emitting LEDs. In particular, in some embodiments,the emitter 504 can include top-emitting LEDs emitting light at about850 nm to 1350 nm.

The emitter 504 can also use super luminescent LEDs (SLEDs) orside-emitting LEDs. In some embodiments, the emitter 504 can employSLEDs or side-emitting LEDs to emit optical radiation at about 1600 nmto about 1700 nm. Emitter 504 can use SLEDs or side-emitting LEDs totransmit near infrared optical radiation because these types of sourcescan transmit at high power or relatively high power, e.g., about 40 mWto about 100 mW. This higher power capability can be useful tocompensate or overcome the greater attenuation of these wavelengths oflight in tissue and water. For example, the higher power emission caneffectively compensate and/or normalize the absorption signal for lightin the mentioned wavelengths to be similar in amplitude and/or effect asother wavelengths that can be detected by one or more photodetectorsafter absorption. However, the embodiments of the present disclosure donot necessarily require the use of high power optical sources. Forexample, some embodiments may be configured to measure analytes, such astotal hemoglobin (tHb), oxygen saturation (SpO₂), carboxyhemoglobin,methemoglobin, etc., without the use of high power optical sources likeside emitting LEDs. Instead, such embodiments may employ other types ofoptical sources, such as top emitting LEDs. Alternatively, the emitter504 can use other types of sources of optical radiation, such as a laserdiode, to emit near-infrared light into the measurement site 502.

In addition, in some embodiments, in order to assist in achieving acomparative balance of desired power output between the LEDs, some ofthe LEDs in the emitter 504 can have a filter or covering that reducesand/or cleans the optical radiation from particular LEDs or groups ofLEDs. For example, since some wavelengths of light can penetrate throughtissue relatively well, LEDs, such as some or all of the top-emittingLEDs can use a filter or covering, such as a cap or painted dye. Thiscan be useful in allowing the emitter 504 to use LEDs with a higheroutput and/or to equalize intensity of LEDs.

The data collection device 112 also includes a driver 520 that drivesthe emitter 504. The driver 520 can be a circuit or the like that iscontrolled by the monitor 118. For example, the driver 520 can providepulses of current to the emitter 504. In an embodiment, the driver 520drives the emitter 504 in a progressive fashion, such as in analternating manner. The driver 520 can drive the emitter 504 with aseries of pulses of about 1 milliwatt (mW) for some wavelengths that canpenetrate tissue relatively well and from about 40 mW to about 100 mWfor other wavelengths that tend to be significantly absorbed in tissue.A wide variety of other driving powers and driving methodologies can beused in various embodiments.

The driver 520 can be synchronized with other parts of the sensor 116and can minimize or reduce jitter in the timing of pulses of opticalradiation emitted from the emitter 504. In some embodiments, the driver520 is capable of driving the emitter 504 to emit optical radiation in apattern that varies by less than about 10 parts-per-million.

The detectors 506 capture and measure light from the measurement site502. For example, the detectors 506 can capture and measure lighttransmitted from the emitter 504 that has been attenuated or reflectedfrom the tissue in the measurement site 502. The detectors 506 canoutput a detector signal 524 responsive to the light captured ormeasured. The detectors 506 can be implemented using one or morephotodiodes, phototransistors, or the like.

In addition, the detectors 506 can be arranged with a spatialconfiguration to provide a variation of path lengths among at least someof the detectors 506. That is, some of the detectors 506 can have thesubstantially, or from the perspective of the processing algorithm,effectively, the same path length from the emitter 504. However,according to an embodiment, at least some of the detectors 506 can havea different path length from the emitter 504 relative to other of thedetectors 506. Variations in path lengths can be helpful in allowing theuse of a bulk signal stream from the detectors 506. In some embodiments,the detectors 506 may employ a linear spacing, a logarithmic spacing, ora two or three dimensional matrix of spacing, or any other spacingscheme in order to provide an appropriate variation in path lengths.

The front-end interface 508 provides an interface that adapts the outputof the detectors 506, which is responsive to desired physiologicalparameters. For example, the front-end interface 508 can adapt a signal524 received from one or more of the detectors 506 into a form that canbe processed by the monitor 118, for example, by a signal processor 510in the monitor 118. The front-end interface 508 can have its componentsassembled in the sensor 116, in the monitor 118, in connecting cabling(if used), combinations of the same, or the like. The location of thefront-end interface 508 can be chosen based on various factors includingspace desired for components, desired noise reductions or limits,desired heat reductions or limits, and the like.

The front-end interface 508 can be coupled to the detectors 506 and tothe signal processor 510 using a bus, wire, electrical or optical cable,flex circuit, or some other form of signal connection. The front-endinterface 508 can also be at least partially integrated with variouscomponents, such as the detectors 506. For example, the front-endinterface 508 can include one or more integrated circuits that are onthe same circuit board as the detectors 506. Other configurations canalso be used.

The front-end interface 508 can be implemented using one or moreamplifiers, such as transimpedance amplifiers, that are coupled to oneor more analog to digital converters (ADCs) (which can be in the monitor118), such as a sigma-delta ADC. A transimpedance-based front-endinterface 508 can employ single-ended circuitry, differential circuitry,and/or a hybrid configuration. A transimpedance-based front-endinterface 508 can be useful for its sampling rate capability and freedomin modulation/demodulation algorithms. For example, this type offront-end interface 508 can advantageously facilitate the sampling ofthe ADCs being synchronized with the pulses emitted from the emitter504.

The ADC or ADCs can provide one or more outputs into multiple channelsof digital information for processing by the signal processor 510 of themonitor 118. Each channel can correspond to a signal output from adetector 506.

In some embodiments, a programmable gain amplifier (PGA) can be used incombination with a transimpedance-based front-end interface 508. Forexample, the output of a transimpedance-based front-end interface 508can be output to a PGA that is coupled with an ADC in the monitor 118. APGA can be useful in order to provide another level of amplification andcontrol of the stream of signals from the detectors 506. Alternatively,the PGA and ADC components can be integrated with thetransimpedance-based front-end interface 508 in the sensor 116.

In another embodiment, the front-end interface 508 can be implementedusing switched-capacitor circuits. A switched-capacitor-based front-endinterface 508 can be useful for, in certain embodiments, itsresistor-free design and analog averaging properties. In addition, aswitched-capacitor-based front-end interface 508 can be useful becauseit can provide a digital signal to the signal processor 510 in themonitor 118.

As shown in FIG. 8, the monitor 118 can include the signal processor 510and a user interface, such as a display 512. The monitor 109 can alsoinclude optional outputs alone or in combination with the display 512,such as a storage device 514 and a network interface 516. In anembodiment, the signal processor 510 includes processing logic thatdetermines measurements for desired analytes, such as glucose, based onthe signals received from the detectors 506. The signal processor 510can be implemented using one or more microprocessors or subprocessors(e.g., cores), digital signal processors, application specificintegrated circuits (ASICs), field programmable gate arrays (FPGAs),combinations of the same, and the like.

The signal processor 510 can provide various signals that control theoperation of the sensor 116. For example, the signal processor 510 canprovide an emitter control signal to the driver 520. This control signalcan be useful in order to synchronize, minimize, or reduce jitter in thetiming of pulses emitted from the emitter 504. Accordingly, this controlsignal can be useful in order to cause optical radiation pulses emittedfrom the emitter 504 to follow a precise timing and consistent pattern.For example, when a transimpedance-based front-end interface 508 isused, the control signal from the signal processor 510 can providesynchronization with the ADC in order to avoid aliasing, cross-talk, andthe like. As also shown, an optional memory 518 can be included in thefront-end interface 508 and/or in the signal processor 510. This memory518 can serve as a buffer or storage location for the front-endinterface 508 and/or the signal processor 510, among other uses.

The user interface 112 can provide an output, e.g., on a display, forpresentation to a user of the data collection device 112. The userinterface 112 can be implemented as a touch-screen display, an LCDdisplay, an organic LED display, or the like. In addition, the userinterface 112 can be manipulated to allow for measurement on thenon-dominant side of patient. For example, the user interface 112 caninclude a flip screen, a screen that can be moved from one side toanother on the monitor 118, or can include an ability to reorient itsdisplay indicia responsive to user input or device orientation. Inalternative embodiments, the data collection device 112 can be providedwithout a user interface 112 and can simply provide an output signal toa separate display or system.

A storage device 514 and a network interface 516 represent otheroptional output connections that can be included in the monitor 118. Thestorage device 514 can include any computer-readable medium, such as amemory device, hard disk storage, EEPROM, flash drive, or the like. Thevarious software and/or firmware applications can be stored in thestorage device 514, which can be executed by the signal processor 510 oranother processor of the monitor 118. The network interface 516 can be aserial bus port (RS-232/RS-485), a Universal Serial Bus (USB) port, anEthernet port, a wireless interface (e.g., Wi-Fi such as any 802.1xinterface, including an internal wireless card), or other suitablecommunication device(s) that allows the monitor 118 to communicate andshare data with other devices. The monitor 118 can also include variousother components not shown, such as a microprocessor, graphicsprocessor, or controller to output the user interface 112, to controldata communications, to compute data trending, or to perform otheroperations.

Although not shown in the depicted embodiment, the data collectiondevice 112 can include various other components or can be configured indifferent ways. For example, the sensor 116 can have both the emitter504 and detectors 506 on the same side of the measurement site 502 anduse reflectance to measure analytes. The data collection device 112 canalso include a sensor that measures the power of light emitted from theemitter 504.
